To all whom it may concern:

Be it known that I, JOHN S. DUNLAP, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illi nois, haveinvented a new and useful Egg- Beater, of which the following is aspecification.

This invention relates to egg-heaters; and has for an object to providea beater embodying new and improved features of simplicity, durability,utility, and efficiency.

A further object of the invention is to provide a beater having animproved form of resilient dasher adapted to conform to the shape of theinterior of the bowl or other vessel in which it is being used.

It is well known that as a liquid is rotated it is thrown by centrifugalforce to the sides of the vessel, at which place it assumes its greatestdensity.

It'is an object of the invention to provide a beater which may be usedin connection with a bowl of ordinary shape and with the dasher-bladealways disposed in the liquid at its greatest densit A further object ofthe invention is to provide an improved form of gearing for driving thebeater and improved means for mounting the gear and connecting it to thedasher.

With'these and other objects in view the present invention consists inthe combination-and arrangement of parts, as will be here- "iiiafter..fully described, shown in the accomepaii ying drawings, and particularlypointed -.o ut;in the. appended claims, it being underat;chan es in-theform, proportion, minor etails may be made without from the spirit orsacrificing any of tages of the invention.

v drawings, Figure 1 is a perspective view-e ;the improved egg-beaterapplied to a conventional bowl shown in section. Fig. 2 is alongitudinal sectional view of a modified form of the improved'beater.Fig. 3 is another modification of the beater. Fig. 4 is a modified formof the dasher.

The improved egg-beater forming the sub-* ject-matter of thisapplication comprises a bar 10, bent for the application of the handle11 at one end at substantially right angles to the bar. Opposite thehandle the bar is bent to form the U-shaped bracket12, in the 0ppositearms 13 and 14 of which the dashershaft 15 is journaled, as at 16 and17. Within the bracket the pinion 18 is mounted upon the shaft in anyapproved manner, as by the screw-threads 19, and having the gearcogs 20.

U on the bar is provided a pivot 21, upon Whic h is rotatably mountedthe gear 22, provided adjacent its periphery with apertures 23, engagingthe cogs of the pinion 18 and having a crank-arm 24 to operate it.

At the end opposite the pinion 18 a hub 25 is secured to the shaft andwhich carries a thin and relatively flexible blade or plate 26, havingapertures 27 therein of any desired form, number, or order ofarrangement. The flexible blade or dasher 26 is disposed atsubstantially right angles to the shaft 15 and is secured to the hub 25at a point intermediate its ends, so as to permit the opposite arms ofthe dasher to conform to the interior walls of a containing vessel.

To the bar may be secured a disk 28, having stamped near its periphery aball-race 29, and the gear-wheel may be provided with an opposedball-race 30, as shown in Fig. 2, and therein may be disposed the seriesof balls 31.

Instead of 'ournaling, as at 16, the end of the dasher-s aft directly inthe arm 13 a plu 32, having a concavity, may be engaged in t e arm, asin Fi 2, and a ball 33 unite the plug and end of t e shaft by engagingthe concavity of the plug and a similar concavity in the end of theshaft. The gear may also be formed by turning the periphery into aflange 34, as in Fig. 3, and forming the apertures 23 throu h theflange, in which case gear-cogs 20 wi 1 stand perpendicular to the planeof the pinion 18". The dasher-blade may also be twisted somewhat from aplane, as at 26, to assume the form of a propellerscrew.

From the foregoing it will be readily understood that the blade of thedasher in operation conforms to the inner surface of the vessel in whichit is being used and that while named and described as an egg-beater itwill be understood that such name is used only for brevity andclearness, the device bein equally adapted for whipping cream, ca e, andmany other materials.

Particular stress is laid upon the extreme thinness and flexibility ofthe dasher-blade, whereby the material remains at comparative rest whilebeing beaten, the blade cutting the material as differentiated fromcreating a great commotion and violently agitating the entire qliantity.Instead of using the single plate- 'ke blade a plurality of 2 5 mountedto rotate ad engagement with the pinion and means for M a w, 0262smaller blades or wings may of course be substituted.

Havin thus described the invention, what is claime is 5 1. An egg-beatercomprising a shaft having a perforated dasher secured thereto andnormally disposed at right an les to the shaft, said dasher beingrelative y thin and flexible to permit the opposite ends thereof- 10 tobe deflected upwardly in contact with the interior Walls of a containingvessel when placed within the latter, and means for rotating the shaft.

2. An egg-beater comprising a bar-having 1 5 a handle at one end andwith the opposite end bent to form a U'-shaped bracket, a dasher-'shaft'journaled in the opposite arms of the bracket, a pinion mountedupon the shaft within the bracket, a resilient blade mounted upon theshaft'and adapted to conformsubstantially to the interior of acontaining vessel, a disk mounted upon the bar and provided with anannular ball-race, a gear-wheel provided with an opposing ball-race and'acent the disk and in rotating the gear. M 3. An egg-beater comprisinga shaft, a

dasher secured to the shaftt and normally disposed at substantiallyright angles thereto, 0

said dasher being relative y thin and flexible to permit the arms of thedasher to conform to the interior walls of a containing vessel,- andmeans for rotating the shaft.

4. An egg-beater comprising a shaft, a 3 5 dasher secured to the shaftand normally disposed at substantially right angles thereto, said dasherbeing relatively thin to permit the arms of the dasher to conform to theinterior walls of a containing vessel, and means 40 for rotating theshaft.

5. An egg-beater comprising a shaft, a dasher secured to the shaftan'dconsistingof a flat relatively thin cutting-blade the front andrearedges of which are disposed in'the 5 same horizontal plane, saiddasher having its major axis disposed substantially parallel with theplane of its movement, an'd'means for rotating the shaft.

In testimony that I claim the foregoing as JP ./3, ya/p y j/d)
